Are you fed up of your skinny ribs sticking out like a set of granny fingers? Then stick around! Because today I will be teaching you how to gain muscle around the ribs.

Gaining muscle around the ribs requires resistance training to target serratus anterior, lats, pecs, and external oblique muscles. Additionally, a caloric surplus and high protein intake of 1.2 grams of protein per pound of body weight should also be consumed on a daily basis to fuel muscle growth.

I use to be a skinny guy myself.

My scrawny ribs made me self-conscious. And I sure as hell wasn’t going to take my shirt off in public! But through research and (a lot) of trial and error, I managed to pack some muscle onto my skinny frame.

So I know you can too!

Are you ready to follow in my footsteps?

Let’s go!

I gained muscle around the ribs

(Left)- One of the rare occasions I actually did take my shirt off in public!

What Are The Muscles Around The Ribs?

First, let’s identify the muscles which (should) cover the ribs.

Not one single muscle is responsible for covering your rib cage. In fact, 4 distinct muscles are responsible for enveloping the ribs.

The muscles around the ribs are the:

  • Serratus anterior.
  • Latissimus dorsi.
  • Pectoralis minor.
  • External obliques.

Combined together, this group of muscles adds muscle mass to the sides of your torso.

Therefore, it is essential to train these component muscles if you want to gain muscle around the ribs!(1)

And when you know how each muscle functions, you will know which exercises to perform (more on that later)!

First, you should know where each muscle is located and what they do.

Serratus Anterior

train the serratus anterior to gain muscle around the ribs

The serratus anterior is also known as the boxer’s muscles.

It attaches to your rib cage (ribs 1 to 9) and scapula (shoulder blade). It functions to pull the scapular forward.(2)

Any movement which arcs your upper arm forward (horizontally around the torso) will engage the serratus anterior.

The serratus anterior is mostly covered by the other 3 muscles below.

But with training, it can become visible. And this will help to cover up those ribs!

Latissimus Dorsi

train the latissimus dorsi to gain muscle around the ribs

The latissimus dorsi is also known as the wing muscles.

It attaches onto the upper arm and the lower back, whilst running across the back of your lower rib cage (ribs 9 to 12).

The latissimus dorsi functions to pull the scapular backward and downwards.(3)

Movements which arc your upper arm downward (vertically along the torso) will engage the latissimus dorsi.

When you thicken the latissimus dorsi, it will cover up the back of your rib cage (making the back of the ribs less visible!)

Pectoralis Minor

the pectoralis minor is an upper rib muscle

The pectoralis minor is also known as the lower pecs.

It attaches onto the upper rib cage (ribs 3 to 5) and the scapular.

The pectoralis minor functions to pull your scapular forward.(4)

Movements which arc your upper arm forward (horizontally around the torso) will engage the pectoralis minor.

The pectoralis minor partly covers the serratus anterior. Therefore, training the pectoralis minor with the serratus anterior will help to cover up the upper rib cage!

External Obliques

train the external obliques to gain muscle around the ribs

The external obliques are a group of muscles also known as the outer abdominals.

They attach onto the lower rib cage (ribs 5 to 12) and the front of the lower torso.

The external obliques function to rotate your torso horizontally.(5)

Therefore, movements that rotate your trunk will engage the external obliques. Additionally, movements which arc your trunk diagonally downwards will also engage the external obliques.

Gaining mass in the external obliques will serve to make the front of your lower ribs less visible!

Resistance Training Exercises To Gain Muscle Around The Ribs

Great!

Now you know which muscles cover up your rib cage!

Next, you will learn how to build these muscles.

In order to do so, you will need to perform resistance training. But don’t worry, I have a list of exercises you can do (see below).

Serratus Anterior/Pectoralis Major ExercisesLatissimus Dorsi ExercisesExternal oblique exercises
Push up plusPull upSide bend
Bench pressLat pulldownRotating crunch
DipsOblique cable twist
Chest flys

Combined, these exercises will work your serratus anterior, latissimus dorsi, pecs minor, and external obliques.

1. Pull Ups For Bigger Lats

The Perfect Pull Up - Do it right!

The pull-up is arguably one of the best exercises you can do to develop your lats. All you need is a horizontal bar and your own body weight.

I use and recommend the Sports Royal Power Tower (you can find the customer reviews here).

Unlike a doorway pull-up bar, a tower won’t damage your property (I’ve had a bar tear down my doorframe in the past!).

How I used pull-ups to build muscle around my ribs.

However, the pull-up can be challenging for beginners.

You can try using resistance bands like these Undersun’s (you can find the cheapest price here) to help you master assisted pull-ups first.

That being said- master the pull-up and you will be able to add serious muscle mass onto the lower back of the rib cage!

Check out my article to learn how to successfully do a pull-up if you cannot currently do one!

2. Lat Pull Downs Are Also Effective For The Lats

Lat Pull Downs For Back Hypertrophy (Correct Form)

The lat pulldown is another awesome exercise to engage your lats.

The movement is similar to the pull-up. But instead of pulling your own body weight, you are pulling on weights.

This allows you to adjust for a lighter weight.

And this can make the lat pull down more suitable if you are a beginner. That’s because you can start by pulling on a lighter weight!

The lat pulldown is most commonly performed on a pull-down machine. But you can also use resistance bands for a great home workout.

And just like the pull-up, the lat pull down will develop the muscles in the lower back of your rib cage!

3. Push Up Plus To Hit The Serratus Anterior

Push-Up Plus | Push-Up Variation

The pushup plus is an excellent exercise to train your serratus anterior.

Why?

The peak of the pushup plus is very effective at specifically targeting the serratus anterior. And this will help you to gain muscle in the upper ribs.

Additionally, it is a bodyweight exercise. And this means you can perform the push-up plus at home!

If you are a beginner, I would recommend you master the normal push-up first. Once this has been achieved, you can work on the push-up plus.

And for further progression, you can incorporate a resistance band into the movement!

Simply wrap a band around your back and position the handles onto the ground. Then use your hands and body weight to keep the band securely planted into the ground. Now push into a push-up plus!

4. Bench Press To Train The Pecs

How to Perform Bench Press - Tutorial & Proper Form

The bench press is a similar movement to the push-up plus.

This exercise will engage the serratus anterior and the pectoralis minor. And developing these muscles will hide those upper ribs.

Unlike the pull-up plus, it is easier to increase the weight on a bench press. Simply add more weight plates!

However, the downside to the bench press is that it requires specific gym equipment (i.e. the barbell and rack!).

How dumbbells and a bench helped me to build muscle around my ribs.

To do this at home, you’ll need a good weight bench like the Flybird (you can find the cheapest price here).

You’ll also need weights of course.

I prefer dumbbells over a barbell because they’re cheaper and doesn’t require much space.

I would stay away from the cheap plastic dumbbells though (what you see in the pic above). Their price tag may look attractive, I found the plates often crack within 2 years of heavy use (I’ve had to replace 2 sets already).

A set of good iron dumbbells like these Yes4All spinlocks (you can find the cheapest price here) will last a lifetime and they only cost around 20 bucks extra.

5. Chest Dips For The Lower Pecs

How to Do a Chest Dip | Chest Workout

The dip is another great exercise to add muscle mass to your upper ribs.

The movement of the dip is similar to the bench press. And this makes it great for emphasizing the serratus anterior and pectoralis minor.

The great thing about the dip?

It’s versatility!

It’s primarily a bodyweight exercise. All you need is your body and a dipping station (a chair will do!)

Once your body weight becomes too easy, you can add more weight!

Simply hold a dumbbell between your legs. Alternatively, if you don’t have dumbbells, just find a heavy household object!

How dips helped to to build muscle around the upper body.

If you get the Sports Royal Power Tower (mentioned above), then you can use it to do dips too!

You can check out my other article to find out which chest area the dips focus on.

6. Chest Flys To Train The Mid Pecs

How To: Dumbbell Flys On A Flat Bench

The final chest exercise on this list is the chest fly.

Just like the previous chest exercises, the pec fly will target your serratus anterior and pectoralis minor.

But the exaggerated horizontal arcing movement of the chest fly makes it ideal to target the serratus anterior specifically.

This makes the chest fly an effective way to add muscle to the upper ribs.

However, this exercise requires dumbbells or resistance bands to perform. Thus making it slightly less convenient for homework out.

The Flybird bench and Yes4All dumbbells mentioned above work great for flys!

7. Side Bends For The External Obliques

How to Do a Dumbbell Side Bend | Ab Workout

The side bend is a popular exercise to develop your external obliques. And this will allow you to gain muscle in your lower ribs.

This exercise will require either a set of dumbbells or some resistance bands.

If you can get hold of either equipment, side bends are an awesome beginner-friendly way to work your obliques!

Simply start with low weight and work your way up.

Alternatively- find a heavy household object to replace the dumbbells!

8. Rotating Crunch To Train The Obliques

How to do a Rotation crunch - Andy Frisch

The rotating crunch is similar to the side bend.

It also works the external obliques to build muscle in your lower ribs.

The crunch is primarily a bodyweight exercise. And this makes it a convenient alternative to the side bend (which requires an external weight).

If you want to ramp things up a gear, you can hold a weight whilst you perform the rotating crunch!

When you do this, you will give your obliques a real workout!

9. Oblique Cable Twist For The Abs

How to perform an Oblique Twist properly

Finally, we have the oblique cable twist.

Just like the side bend and rotating crunch, the oblique twist will also work your external obliques.

But the major difference is that the cable twist involves a horizontal core rotation.

In comparison, the side bend and rotating crunch involve a diagonal core rotation.

And this difference in the rotation will focus the workout on the different areas of the external obliques.

Therefore the cable twist is an excellent complementary exercise to develop the muscles in your lower rib cage!

Example Training Programme To Gain Muscle Around The Ribs

So now you have 9 exercises. But how do you include them in a training plan?

Don’t worry I got you covered!

Whenever you make a weight training plan to gain muscle, you need to consider how many sets to perform every week.

Generally speaking, it is reccomened to complete around 10-20 sets per muscle per week. And this is optimal for muscle growth.(6)

As a beginner, I would recommend you stick towards the lower end of the spectrum. This is because your muscles are probably not yet adapted to weight lifting yet.

12 sets per muscle per week is good!

If you would like to learn how much weight you should be lifting, check out my guide on choosing the right weight to build muscle!

example workouts to gain muscle around the ribs
Each muscle (serratus anterior, latissimus dorsi, pectoralis minor, external obliques) receives 12 sets per week.

This training plan can be stand-alone.

However, I would highly recommend incorporating other exercises too.

Ideally, you should be working all the muscles across your body. And this will ensure balanced muscle development.

An efficient way to do whole body weight lifting is to perform compound lifts.

Nutrition To Gain Muscle Around The Ribs

Additionally, you will also need to follow a suitable nutrition plan to gain muscle around the ribs.

Now, training is great.

But if you do not combine your workouts with suitable fuel, you simply will not gain muscle.

I will now share a basic nutrition plan to gain muscle.

You may be interested in my other post to find out if skinny guys should go on a bulk or cut.

5-10% Caloric Surplus

Being in a caloric surplus means consuming more calories than your total daily maintenance calories.

When you do this, your body will convert the extra calories into muscle (assuming you are training sufficiently).

And this will fuel the muscle-building process in your serratus anterior, lats, pectoralis minor, and external obliques.

Furthermore, limiting your surplus to 5-10% above maintenance will prevent your body from storing excess fat.

In addition to being in a caloric surplus, you should also follow a macronutrient profile similar to the one below:

Macronutrient% Of Total CaloriesApproximate Grams Per DayReasonExamples
Protein35%1.5g per pound of lean body weightProtein is required to build muscle. If you under consume protein, your body will not build muscle.Lean red meat, poultry, fresh fish and shell fish, legumes, soy products.
Complex Carbohydrates35%2.5g per pound of body weightComplex carbs fuel your workouts. Aim to consume most of your carbs during the day (especially pre and post-workouts).Potatoes, whole grain pasta/bread, legumes.
Healthy Fats20%0.4g per pound of body weightHealthy fats also fuel your workouts. But they are also required for hormone production and muscle growth.Oily fish, nuts, seeds, vegetable oils, avocados.
Fibre10%6 portions of fruit and vegDietary fiber will slow down your digestion. This allows your body to absorb the maximum amount of nutrients from your meal.Fresh fruit and veg

Conclusion

Thats todays post finished!

I have taught you how to gain muscle around the ribs.

You will need to undertake a resistance training program that focuses on developing the serratus anterior, latissimus dorsi, pectoralis minor, and external oblique muscles.

In addition to this, you should also follow a nutrition plan which is conducive to muscle building. Furthermore, the ideal nutrition plan should put you in a mild caloric surplus. It should also contain a balanced intake of protein, complex carbs, healthy fats, and dietary fiber.

Having visible ribs is a common source of grief for many skinny people. Indeed, I had the same problem 2 years ago! But I was able to pack on muscle to cover those ribs. And I know you can too!
